How about if you put each column into a list, and then after finishing, iterate through all lists to produce the row? Only thing is that everything will be stored in memory. But you could always add a bunch of swap, and that will take care of it. :)
http://library.gnome.org/devel/glib/stable/glib-Doubly-Linked-Lists.html Add swap on the fly. http://www.tldp.org/FAQ/Linux-FAQ/partitions.html#add-temporary-swap-space Or, use gdbm. Here is a read example. http://www.vivtek.com/gdbm/example.html Shouldn't be too hard to write data. brian On Thu, Mar 20, 2008 at 11:55:45AM -0700, Carl Boettiger wrote: > Hi, > > This isn't a linux question directly but I'm going to abuse the > generosity and knowledge on this list and ask anyway: > > I'm running a c code where I'd like to print out data to a file in a > matrix form.
